Lack of content and last mile ISP support are the biggest issues at the moment.
On cable, sure. On DSL, PPPoE can tunnel IPv6 just as well as IPv4 without any intervention from the telephone company, only thing required is a 3rd-party ISP that supports PPPoE-IPv6.
Content-wise, I doubt we are going to see anything exclusive to IPv6 and even if there was, with 6to4/4to6 bridges would render that mostly moot.
